Hehe that's pretty cool. I do have unlimited data so I might be able to use it at home. =D
Edit: Woops Marketplace die for some reason.
What carrier are you on? I have unlimited data but is the if you went over 3GB we slow your phone to a crawl bait a switch >=(.
As far as features, Thumba without a doubt. Pictures Hub has an easier to use UI, however. Apict is a nifty Instamatic clone, but I haven't used it in months, and last time I did, it needed a few more features. Lastly, Bubblegum is a free Instagram clone, and it has a few effects, and best I remember posts directly to Facebook and Twitter. (I've only used it for the latter.)
Sweet when my phone finish recharging I'll give all of them a try, I have this bad habit of when my phone is critically low of battery I have this urge to play Angry Birds until the phone dies.
Not sure if that was directed at me or not, but I did leave myself an out and said that I'd give the demo a spin. Sometimes playing the demo on your own device that you're used to gives you a different perspective than a quick game on someone else's device. It's a nifty game, I'm just not spending $5 on it. I typically get my games as deal of the week, barring some good non-Live indie games that don't get enough press.Angry Birds ? That's not healthy. I remember someone saying what's all the fuss about Angry Birds it's nothing special and they wouldn't be buying it.
Mentioning no names but the said person isn't too far away.
